I fount what is potentially two in game bugs, or what Im assuming as bugs.
First off, if you tell your constable to train recruits, and you leave for a while, especially somewhere far away and come back, he appears to "forget" to continue to train the troops, even if there's treasury money. This becomes incredibly annoying because then you have to tell him again to train recruits, and if you go too far again, he forgets, also if you go back into the castle soon after telling him to train the recruits, even if you haven't went far from the castle at all, he still forgets and you must tell him AGAIN to train troops.
The second bug I believe is a bug, is that I've got an independent kingdom set up, and it's all fine and dandy until the holy roman empire comes and takes the castle that my counsel is at. So I lose my primary castle that holds the counsel, but one of my vassals lets me use his castle as the new place that my counsel can form. I go to the new primary castle, and I only have my minister, so I tell him him to hire me a new constable and financial advisor. I wait a few days and go back, and theres no constable, no advisor, and I go back to see if I can still hire staff, and I can. It constantly takes out the 10-20 cash for them, but then they never show up at my primary castle that my counsel are supposed to meet at. I've tried it multiple times, left the castle, and stayed at the castle, and it always loops back where I can hire a constable and a financial advisor, but it never delivers them to me now matter how many times I pay the 10-20 cash to the minister, and it's the same person that's recommended each time for each position if that helps.
These appear like bugs to me but I could be wrong.
